| Abstract: | A reappraisal of oxygen uptake by Sarotherodon mossambicus was undertaken using a continuous flow respirometer. Measurements were obtained over the temperature range 16°C–37°C for fish weighing between 10 g and 150 g. Oxygen uptake was converted to energy equivalents ( Q ox) using the value 13.68 J mg O2–1and the routine metabolic energy expenditure can be described by the equation E =0.0086 t 2 0783 M 0 652 where E is the energy requirement for routine metabolism expressed in J h-1, t the temperature in °C and M the mass in g. |
